There’s also the upcoming Fantasy Strike, which re-purposes characters from Street Fighter and Guilty Gear (just a little too closely thus to their inspirations, frankly) which has a simple control scheme.
The defunct indie fighting game Rising Thunder, conceived with Maplestory M Mesos the founders on the Evo tournament themselves, used the PC keyboard since it's inspiration, in lieu of an arcade stick. Characters had three attack buttons and three special attack buttons, set up clear as day for their keyboard. Confusion was immediately eliminated as players knew exactly what what food was in their arsenal. 
Rising Thunder had very restricted move sets (there's ultimately reasons we supply these buttons and motions to fight games), however it had every one of the core elements Maplestory M Mesos for sale of the fun fighting game. Most importantly, it allowed individuals who had never tried the genre before to instantly begin and view the appeal of going toe-to-toe with another player by using an equal stage. It allowed you believe strategically without getting above the hump of memorizing a large quantity of complicated motions.
